This page answers the questions covered by the article Vapor Degreasing Explained - Enviro Tech International, Inc. on envirotechint.com. The article is the full, canonical source.
Direct answer: According to Enviro Tech International, vapor degreasing is a solvent cleaning process that boils a solvent to create a vapor, which condenses on parts, dissolves soils, and then drips off by gravity to be recycled. The article states a single compact machine performs the rinsing, scrubbing and drying steps without water, using the solvent to do the cleaning. It positions the method as requiring fewer machines, less floor space, energy and cleaning time than processes that use separate machines for those steps.
According to the article, vapor degreasing works by boiling a solvent to create a vapor, which then condenses on the surface of each part. Once on the surface, the solvent dissolves soils, and the liquid solvent and soils drip off the part by gravity to be recycled back into the boiling solvent for additional cleaning.

The article states that other cleaning processes require multiple machines for rinsing, scrubbing and drying. According to the article, the need for multiple machines means higher upfront cost, higher energy costs, longer cleaning time and more floor space to accommodate the machinery.

The article describes a vapor degreaser as a metal apparatus with heating elements at the bottom and cooling coils toward the top. The heating element brings the liquid solvent to a boil, turning it gaseous, while the cooling coils prevent the vapor from escaping and create an atmosphere. After parts are lowered into the atmosphere, vapor condenses on them, and when lifted out the liquid drips off by gravity back into the reservoir, leaving the parts dry and clean of soils.

The article states that chemical solvent cleaners such as n-Propyl Bromide (nPB) and fluorinated solvents are used instead of water in the vapor degreasing process. According to the article, more recent fluorinated additions including EnSolv NEXT solvents are more environmentally responsible alternatives to earlier degreasing solvents.

The article states that vapor degreasing is not dangerous so long as proper safety protocols are followed. It recommends that a floor draft system be installed for ventilation. The article also states to always use personal protection equipment and to consult the safety data sheet included with the solvent shipment for specific handling and usage instructions.

The article describes ultrasonic degreasing as an optional further step used if oil and flux remain on parts after the basket is lifted from the gaseous atmosphere. A separate reservoir contains solvent and a device that creates micro vibrations in the liquid; when the basket is fully submerged, the vibrations act like scrubbing to help remove contaminants. After holding the parts for some time, the basket is lifted into the atmosphere and then slowly out, as without the ultrasonic tank.
